The San Francisco Police Officers Association is offering a $10,000 reward for anyone providing information that leads to the arrest and conviction of the person suspected of brutally beating an 88-year-old woman and leaving her unconscious on the Visitacion Valley Playground early Tuesday morning.

Officials announced their reward Thursday night. A witness found San Francisco resident Yik Oi Huang bloodied and unresponsive with multiple fractured bones to her head and ribs laying near the slide on the playground.

Family members believe she was attacked around 7 a.m. during her normal exercise routine of walking around the park near her Visitacion Valley residence.

Police said they were responding to a report of a burglary on the 1000 block of Visitacion Avenue in the Ingleside District when they were flagged down by the witness, said Officer Adam Lobsinger, an SFPD public information officer.

Huang remained in critical condition at San Francisco General Hospital on Thursday.

“This abhorrent crime strikes a nerve with every law abiding resident of our city, respect and reverence for our elderly is an essential component to a civilized society and we wish Ms. Huang a speedy recovery,” said Tony Montoya, the president of the police union in a statement. “We urge anyone with information about this cowardly act to call (the San Francisco Police Department) or 911 immediately.”

Huang’s assault prompted more than 10 San Francisco residents — including Huang’s granddaughter Sasanna Yee — to plead with officials at the San Francisco Police Commission meeting on Wednesday night. Each called for a number of recommendations for police to improve the community’s sense of safety, including increasing early-morning patrols in the Visitacion Valley community, create a substation in the neighborhood, and hire more bilingual officers to better serve the community.

The SFPOA is scheduled to announce specific actions and recommendations to “make Visitacion Valley safer” at a Friday morning press conference.

The case is being investigated by the police department’s Special Victim’s Unit because the Huang is elderly, police said.

Anyone who has information about the assault may call the anonymous tip line at 415-575-4444.
